Arrive in BZE and rent a car and head toward the rainforest in Dangriga. Along the way stop at the Baboon Sanctuary (These are actually howler monkeys but the slaves that were brought to Belize called them baboons after the monkeys in their own country)
In Dangriga there are a few options we stayed with Steven at Pineapple Hill he has multiple listings under Pineapple Hill Belize and his 50 acre property is stunning and he has done more with it since this video was posted in 2018. I have also heard good things about Sleeping Giant Rainforest Lodge If you want to pay a little more to be pampered. This is likely a full day depending on when you arrive there is an awesome roadside bar and grill called Green Hills just down the road in Middlesex.
Day 2: Stay in Dangriga and explore we missed out on ATM cave but if the water is right this is supposed to be a once in a lifetime experience. If like us you miss out on that opportunity Angel Falls Belize can organize a great zipline tour over the valleys in the rain forest there are a few roadside hikes to waterfalls including Billy Barquedier Waterfall. Head into Armenia for dinner Las Palapas Restaurant is suggested.
